I'm confused, why is it classified as a forever chemical? It's not PFAS.

“Forever chemicals” are a category. It’s not a term that’s meant to be synonymous with PFAS. PFAS is just an example of one.

Interesting. Thanks!

Yep, @gravitas_deficiency@sh.itjust.works knows what's up. PFAS are one group of forever chemicals. While 2,3,7,8-tetrachlorodibenzofuran (TCDF) shares many characteristics with “forever chemicals” like PFAS, including persistence, bioaccumulation, and toxicity, it belongs to a different chemical class (Persistent Organic Pollutants aka POPs). Nonetheless, its environmental and health impacts are significant, and efforts are needed to reduce its presence in the environment!
